The results of the May 6 primaries in the final two states offering any substantial delegate counts have weakened the New York senator’s argument of electability and greatly reduced her chances of catching Democratic frontrunner Barack Obama.

With Clinton unable to match Obama in delegates, her campaign has turned to trying to convince undecided superdelegates that she is the stronger candidate against Republican nominee John McCain in November.

Addressing a crowd of supporters in Indiana, Clinton offered a conciliatory tone, but ultimately dispelled any notion that the day’s events would bring an end to her campaign.

The New York senator framed her 51 percent to 49 percent victory as a “tie-breaker,” and indicated that it was now “full steam to the White House.”

Meanwhile, Obama spoke to supporters in North Carolina after winning the state 56 percent to 41 percent, offering congratulations to Clinton on her win in Indiana, long before the state had been called in her favor.

With six primaries remaining, Clinton’s options for catching her opponent dwindled, providing her with few alternatives to attempting to convince superdelegates to support her, should she be able to seat the disqualified delegates from Florida and Michigan.

This would likely have to occur before the May 20 primary in Oregon, a state strongly favoring Obama.

Despite expected Clinton victories in Kentucky and West Virginia in the next two weeks, a decisive win by Obama in Oregon would give him enough delegates to clinch the Democratic nomination.

Though Clinton was able to pull off a narrow win in Indiana, her argument of electability was weakened by her inability to catch Obama in votes and pledged delegates, putting her at a disadvantage when trying to convince superdelegates that they should support her.

The six primaries to be held over the next month offer few surprises, with polls showing West Virginia, Puerto Rico and Kentucky going to Clinton, while Oregon, Montana and South Dakota will likely going to Obama. This result will leave the candidates essentially where they are now, allowing only a substantial superdelegate shift to help her clinch the nomination.

A late night of reporting from a single county in northwest Indiana delayed a decisive victory for Hillary Clinton, bringing the race to within 20,000 votes. The county attributed the delay to an unusually high number of absentee votes.

The close race comes after a particularly negative month for Obama, including questions regarding his patriotism, his relations with controversial figures and the reemergence of his former pastor Rev. Jeremiah Wright on the national stage. The latter dominated the national news coverage in the week leading up to the primaries.

Hillary Clinton has now altered the requisite number of pledged delegates needed to clinch the nomination from 2,025 to 2,208. This new total includes delegates from Michigan and Florida, states that were disqualified from seating their delegates after breaking Democratic Party rules for rescheduling their primary contests.

The Guardian’s Michael Tomansky sees the May 6 primaries as the “end of the line” for Clinton, but does not see the New York Senator pulling out of the race anytime soon. Rather, he predicts a delegate fight all the way to the Democratic National Convention in late August.

CBS News argues that while Clinton scored the necessary victory in Indiana to keep her campaign alive, it is just barely enough to keep her bid for the nomination going. While Clinton is unlikely to drop out, pressure from undecided superdelegates and party elders may push her to suspend her campaign.

The current spread between the two candidates gives Obama an overall lead of 152 delegates, with only 217 delegates left to earn in the remaining six primaries. Clinton leads in the number of superdelegates by 12, but with only 267 left undecided and Obama outperforming her in recruitment, this lead could soon dissipate.
